Major League Baseball operates as the highest level of professional baseball in the United States and Canada, structured around two distinct entities: the National League and the American League. Each season brings intense competition across these two historic circuits, culminating in the World Series, where the champions of each league face off for the title.
For television viewers and sports fans, tracking this sprawling 162-game regular season requires understanding how the two leagues function independently before converging in the postseason. According to Major League Baseball records, the National League and the American League maintain separate structures, administrative boards, and historical traditions that stretch back over a century before playing under a unified operational banner.
Understanding this structure helps fans navigate broadcast schedules, regional TV magazine listings, and streaming options across local and national networks. Editorial coverage of matchups involving historic franchises like the Chicago Cubs in the National League and the Los Angeles Dodgers in the National League West highlights the enduring appeal of these organizational divisions.
Structure of the National and American Leagues
Major League Baseball is partitioned equally into the American League (AL) and the National League (NL), with each league comprising 15 teams divided geographically into East, Central, and West divisions. Established in 1876, the National League is the oldest extant professional sports league in the United States, while the American League was formally organized as a major league in 1901.
For decades, the two leagues operated under distinct rules, most notably the American League’s adoption of the designated hitter rule in 1973, while National League pitchers continued to bat for themselves. According to Major League Baseball official history, those operational differences largely harmonized following the structural unification under the Office of the Commissioner in 2000 and the universal implementation of the designated hitter in 2022.
Television magazines and sports guides map out weekly schedules based on these divisional alignments. Regional sports networks broadcast the majority of regular-season games for clubs like the Chicago Cubs and the Los Angeles Dodgers, while national broadcasters air marquee matchups weekly across cable and streaming platforms.
Broadcasting and TV Magazine Coverage
Media coverage of Major League Baseball spans local regional sports networks (RSNs), national cable broadcasters like ESPN, TBS, and Fox, and digital streaming packages. Print and digital TV magazines outline these broadcast windows weekly to help viewers track complex daily schedules involving West Coast and Midwest time zones.
Fans following cross-country rivalries or interleague play rely on detailed television listings that specify whether a game streams on platforms like Apple TV+ or Peacock, or airs on traditional linear television. According to Major League Baseball broadcast guidelines, local blackout rules apply to regional broadcasts, directing fans to authorized regional sports networks or MLB.tv for out-of-market games.
Editorial teams in sports journalism curate these broadcast details alongside player statistics, injury reports, and standings updates to provide comprehensive guides for each series throughout the April-to-October calendar.
